Particulate aggregating and surface modification with improved hydrocarbon fluid flow through the aggregated particulates and over solid surface reagents and methods for making and using same

Abstract

Composition and methods using the compositions are disclosed, where the compositions include heterocyclic aromatic amines, substituted heterocyclic aromatic amines, poly vinyl heterocyclic aromatic amines, co-polymers of vinyl heterocyclic aromatic amine and non amine polymerizable monomers (ethylenically unsaturated mononers and diene monomers), or mixtures or combinations thereof reacted with sulfonic acids, alkyl sulfonic acids, sulfosuccinates, sulfamic acids, sulfuric acids or partially neutralized amine or other alkali sulfonate and/or reacted with alpha hydroxyl carboxcylic acids which form coatings that alter self-aggregating properties and/or aggregation propensities of the particles and surfaces. Furthermore, the coating can be used to improve filtration of fluids through particulate matter and it is found that the coating will increase hydrocarbon liquid and gas flow through or over treated particulates and surfaces.

We claim: 
     
       1. A method for improving hydrocarbon liquids and gas flow in subterranean formations or through sand, packing material or particulates by contacting the particles, surfaces and/or materials in the formations, vessel or other means of containing the particles, surfaces and/or materials with a coating composition including 20-70 wt % of the coating composition of one or a plurality of aryl amines, one or a plurality of substituted aryl amines, one or a plurality of polymers or copolymers including at least one monomer vinyl aryl amine, and/or mixtures or combinations thereof reacted with 1-10 wt % of the coating composition of sulfonic acids, alkyl sulfonic acids, sulfosuccinates, sulfamic acids, sulfuric acids or partially neutralized amine or other alkali sulfonate and reacted with 1-10 wt % of the coating composition of an alpha hydroxyl carboxylic acid which form complete or partial coating on the particles, surfaces that result in increased flow through the treated particles, surfaces and/or materials. 
     
     
       2. The method of  claim 1 , wherein the coating composition further includes a carrier. 
     
     
       3. The method of  claim 1 , wherein the amines comprises heterocyclic aromatic amines, substituted heterocyclic aromatic amines, poly vinyl heterocyclic aromatic amines, co-polymers of vinyl heterocyclic aromatic amine and non amine polymerizable monomers, or mixtures or combinations thereof, where the substituents of the substituted heterocyclic aromatic amines are carbyl groups having between about between about 1 and 40 carbon atoms and the required hydrogen atoms to satisfy the valence and where one or more of the carbon atoms can be replaced by one or more hetero atoms selected from the group consisting of boron, nitrogen, oxygen, phosphorus, sulfur or mixture or combinations thereof and where one or more of the hydrogen atoms can be replaced by one or more single valence atoms selected from the group consisting of fluorine, chlorine, bromine, iodine or mixtures or combinations thereof. 
     
     
       4. The method of  claim 1 , wherein the amines comprises aniline and alkyl anilines or mixtures of alkyl anilines, pyridines and alkyl pyridines or mixtures of alkyl pyridines, pyrrole and alkyl pyrroles or mixtures of alkyl pyrroles, piperidine and alkyl piperidines or mixtures of alkyl piperidines, pyrrolidine and alkyl pyrrolidines or mixtures of alkyl pyrrolidines, indole and alkyl indoles or mixture of alkyl indoles, imidazole and alkyl imidazole or mixtures of alkyl imidazole, quinoline and alkyl quinoline or mixture of alkyl quinoline, isoquinoline and alkyl isoquinoline or mixture of alkyl isoquinoline, pyrazine and alkyl pyrazine or mixture of alkyl pyrazine, quinoxaline and alkyl quinoxaline or mixture of alkyl quinoxaline, acridine and alkyl acridine or mixture of alkyl acridine, pyrimidine and alkyl pyrimidine or mixture of alkyl pyrimidine, quinazoline and alkyl quinazoline or mixture of alkyl quinazoline, or mixtures or combinations thereof. 
     
     
       5. The method of  claim 1 , wherein the sulfonic acids, alkyl sulfonic acids, sulfosuccinates, sulfamic acids, sulfuric acids or partially neutralized amine or other alkali sulfonate include without limitation sulfuric acid, sulfamic acid, sulfonic acid, alkyl sulfonic acids such as propane sulfonic acid or dodecylbenzene sulfonic acid, cyclic sulfonic amido sulfonic acids, sulfosuccinates or other partially neutralized salt of the afore mentioned acids. 
     
     
       6. The method of  claim 1 , wherein the alpha hydroxyl carboxylic acid include without limitation citric acid, glycolic acid, and lactic acid or mixture or combination thereof.
